president clinton had said allowing genocide to happen in rwanda was one of his greatest failures in office. we know the president spent time with bill clinton recently. what is your sense how potent this is for president obama and whether or not he would take the step of taking out these facilities before this could happen? >> well i think we obviously known about the threat of syria's chemical weapons capability for a long time and this conflict has been going on now, getting close to two years. so we're a little bit late in the game to finally be worried about what might happen. in fact, there is actually a bigger risk in my view. it will be a tragedy if the weapons are used against the opposition in syria. but the potential for an even larger tragedy exists if the opposition gets hold of these chemical weapons, the terrorist elements in the opposition and sends them outside syria where they could be used by terrorists around the world. so the threat, although our immediate focus is the risk inside syria, i don't think we can ignore. i think america's focus ought to be the threat
